Product details
Overview
P6SMB220AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, rated for 220 V standoff voltage (VWM), 231 V minimum breakdown voltage (VBR), and 328 V maximum clamping voltage (VC) at 1.8 A peak pulse current (IPPM), designed to protect power rails and signal lines in industrial power supplies and automotive ECUs against lightning-induced surges and inductive switching transients.
For engineers reviewing the P6SMB220AHE3_A/I datasheet, P6SMB220AHE3_A/I pinout, P6SMB220AHE3_A/I application, or P6SMB220AHE3_A/I equivalent, this AEC-Q101-qualified TVS offers verified 600 W peak pulse power (10/1000 μs), low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive and industrial PCB designs requiring robust overvoltage immunity without layout redesign.
Technical Context
This device operates as a unidirectional avalanche diode with cathode-band polarity marking, leveraging glass-passivated junction technology for stable clamping performance across -65 °C to +150 °C junction temperature range. Its 100 °C/W junction-to-ambient thermal resistance requires adherence to the specified 0.2" × 0.2" copper pad layout for rated 600 W pulse handling.
The P6SMB220AHE3_A/I delivers fast response time (<1 ns) and low leakage (<1.0 μA at 185 V), enabling protection of sensitive downstream ICs such as microcontrollers and CAN transceivers without signal distortion. It is not bidirectional - no CA suffix - and does not support reverse-biased operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 185 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 209–231 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during transient events. |
| VC (Clamping Voltage) | 328 V at 1.8 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized 10/1000 μs waveform; validates surge robustness. |
| ID (Reverse Leakage) | <1.0 μA at 185 V - Minimal DC loading on source; preserves efficiency in high-impedance bias networks. |
| TJ max. | +150 °C - Enables deployment in under-hood automotive environments and enclosed industrial enclosures. |
| Package | SMB (DO-214AA) - Surface-mount footprint compatible with automated assembly; 5.59 mm × 4.06 mm body size. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode of internal avalanche junction | Connected to protected line; clamps when voltage exceeds VBR relative to anode (ground or lower potential node). |
| Anode | Cathode of internal avalanche junction | Typically tied to ground or common reference; completes clamping path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: 24 V battery-supplied engine control units exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and DC-DC input stage to clamp transients above 185 V. Use Value: Limits peak voltage to ≤328 V during 600 W surges, preventing damage to buck controller ICs and gate drivers. |
Use Scenario: 24 V digital input modules in programmable logic controllers subjected to field-wiring induced surges. IC Role / Device Role / Timing Role: Front-end transient suppressor on isolated optocoupler input side, referenced to system ground. Use Value: Maintains <1.0 μA leakage at 185 V, avoiding false triggering while clamping 1.8 A pulses within 328 V. |
| Telecom DC Power Feeds | Motor Drive Gate Driver Protection |
Use Scenario: -48 V DC power distribution in telecom base station cabinets with long cable runs susceptible to lightning coupling. IC Role / Device Role / Timing Role: Reverse-polarity protected TVS on feed line, oriented to clamp positive transients only.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ220A-E3/5B | Same VWM (185 V), identical SMB package, but lower PPPM (400 W) and higher VC (356 V at 1.6 A). | Limited to lower-energy surge environments (e.g., IEC 61000-4-4); insufficient for ISO 7637-2 Pulse 5a compliance. | Select when cost sensitivity outweighs peak surge margin and AEC-Q101 is not required. |
| 1.5SMC220A | Higher package thermal mass (SMC/DO-214AB), same VWM/VC specs, but RθJA = 30 °C/W vs. 100 °C/W - requires larger pads. | Better sustained power handling but incompatible with dense layouts; not AEC-Q101 qualified. | Choose for industrial AC/DC front-ends where board space allows larger footprint and automotive qualification is unnecessary. |
Compared with SMAJ220A-E3/5B and 1.5SMC220A, the P6SMB220AHE3_A/I uniquely combines AEC-Q101 qualification, 600 W pulse rating, and SMB footprint - making it the only option among the three suitable for space-constrained, automotive-grade 24 V rail protection without derating or layout change.

FAQ
What is the clamping voltage of the P6SMB220AHE3_A/I at its rated peak pulse current?
The P6SMB220AHE3_A/I has a maximum clamping voltage (VC) of 328 V at 1.8 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuits during surge events. The P6SMB220AHE3_A/I maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C) when mounted per the recommended 0.2" × 0.2" copper pad layout.
Is the P6SMB220AHE3_A/I bidirectional or unidirectional?
The P6SMB220AHE3_A/I is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). It conducts only when the cathode is biased positively relative to the anode - meaning it protects against positive transients on a line referenced to ground. Bidirectional variants (e.g., P6SMB220CA) are separate part numbers and are not interchangeable with the P6SMB220AHE3_A/I due to fundamental polarity and circuit behavior differences.
Does the P6SMB220AHE3_A/I meet AEC-Q101 requirements?
Yes, the P6SMB220AHE3_A/I is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's P6SMB datasheet (Rev. 09-Jan-2024, Doc. #88370). It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per JESD22 standards. This qualification applies specifically to the HE3 variant - generic P6SMB220A parts without HE3/HM3 suffixes are not AEC-Q101 certified.
What is the maximum reverse leakage current for the P6SMB220AHE3_A/I at its stand-off voltage?
The P6SMB220AHE3_A/I exhibits a maximum reverse leakage current (ID) of 1.0 μA at its rated stand-off voltage (VWM) of 185 V, measured at 25 °C ambient. This low leakage ensures minimal power loss and avoids false triggering in high-impedance sensing or bias networks. Leakage remains well below 10 μA even at elevated temperatures up to 125 °C, supporting reliable operation in thermally demanding applications.
Can the P6SMB220AHE3_A/I be used in place of P6SMB220A-E3/52?
No - the P6SMB220AHE3_A/I and P6SMB220A-E3/52 are not functionally interchangeable despite sharing core electrical specs. The P6SMB220AHE3_A/I carries AEC-Q101 qualification and uses "I" reel packaging (3200 pcs/reel), whereas P6SMB220A-E3/52 is commercial-grade only and supplied in 750-piece reels. Substituting one for the other risks non-compliance in automotive applications and invalidates qualification-based design validation.
